Whisk the Base: In a medium mixing bowl, whisk together the sourdough discard, sugar, and salt until smooth.
Adjust Consistency: The batter should be pourable, similar to heavy cream. If itβs too thick, whisk in 1 tablespoon of warm water.
Activate: Add the baking soda and whisk vigorously for 30 seconds. The batter should become light, airy, and slightly foamy. Let it rest for 10 minutes.
Heat the Pan: Place a cast-iron skillet or heavy non-stick pan over medium-low heat.
Grease & Set: Generously butter the inside of your crumpet rings. Place them in the hot pan and add a small pat of butter inside each ring.
The Pour: Pour about ΒΌ cup of batter into each ring (fill to about Β½ inch thick).
The Bubble Stage: Cook for 5β8 minutes. Watch for bubbles to rise and pop, forming permanent holes. The crumpets are ready to flip when the tops look dry and set.
The Finish: Remove the rings. Flip the crumpets and cook the tops for just 30β60 seconds until lightly golden.
